According to one embodiment an apparatus may include a. first arched frame and a second arched frame. The first arched frame may include an adjustment mechanism and may be configured to be positioned proximate to the occlusal surface of a user s mandibular arch such that the first arched frame extends beyond the lower cuspids of the user s mandibular arch when the first arched frame is positioned in the user s mouth. The second arched frame may include a receiving mechanism and may be configured to be positioned proximate to the occlusal surface of a user s maxillary arch such that the second arched frame extends beyond the upper cuspids of the user s maxillary arch when the second arched frame is positioned in the user s mouth. The receiving mechanism may be configured to engage the adjustment mechanism to adjust the position of the mandibular arch relative to the maxillary arch.
